joe biden will face off with paul ryan. cnn's political editor, paul steinhauser, joins me now from danville, kentucky. paul, set the stage for us. it's red, white and blue. i have to say, though, i'm looking forward to this one more than the other one because you never know what joe biden is going to say, and that makes for some great television. >> reporter: joe biden often speaks from his heart, no doubt about that. i think this could be maybe a more entertaining debate than last week in denver. those live pictures -- i saw you try to do them at the top of the hour, but you have them now. that building right there, that's what you were looking at inside. here's how it's going to work. first of all, the congressman from wisconsin, paul ryan, in one corner. he will be here later today, don. he arrives later today here in danville. vice president biden coming in tomorrow. both men, as you know, you haven't seen them on the campaign trail much. why? they've been locked down on debate prep. it's a 90-minute debate. martha rad
